It is necessary to solve the separation of impurities such as calcium carbide in kaolin, improve the quality of kaolin products, and meet the purity requirements of ceramic and paper making and other industries. Using the double-liquid layer flotation PTMS magnetic separation method. First, sodium silicate and alkali are added to the clay pulp as dispersant to adjust the properties of the pulp and make the particles dispersed evenly. Then fatty acids are added as traps, carbon tetracloride, and industrial kerosene as a mediator.
The pH value of the pulp is adjusted to the range of 8-12 to emulsion the pulp to form two liquid layers: kaolin-water layer and impurity-organic liquid layer. Finally, pure kaolin is recovered from the liquid phase, calcium carbide from the oil phase, and the used blend (industrial kerosene) can be reused after PTMS magnetic separation removes impurities.
Through the double liquid layer flotation PTMS magnetic separation method, the impurities such as calcium carbide in kaolin are effectively separated, and the purity of kaolin is improved, and the strict requirements of related industries for kaolin quality are met.
